Detailed Description
Preferred embodiments of the present invention will be described in more detail below. While the preferred embodiments of the present invention are described below, it should be understood that the present invention may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
The invention provides a gear shifting control method of a vehicle associated main driving door, which comprises the following steps:
when the vehicle starts, the gear is in a non-P gear, and the vehicle speed is not greater than a first threshold value, judging whether the vehicle receives a first signal, and if the vehicle receives the first signal, controlling the gear to automatically return to the P gear from the non-P gear;
judging whether the vehicle receives a second signal, if so, controlling the gear to automatically return to the P gear from the non-P gear, and when the driver is in gear again, stopping the gear from automatically returning to the P gear and sending a safety prompt to the driver;
when the vehicle speed is not greater than the first threshold value again, and the vehicle receives the first signal, the control gear automatically returns to the P gear from the non-P gear again.
Specifically, the control method is that when the vehicle is in a starting state, the vehicle speed is lower than a first threshold value, and after the vehicle receives a first signal, the gear can return to the gear P from the gear P, so that the condition that the vehicle does not slip in an unmanned state can be ensured, and the driving safety is ensured; in addition, after the vehicle receives the second signal, although the gear is returned to the P gear from the non-P gear, the driver still has control over the gear as long as the driver operates the gear again, so that the normal operation of the vehicle is ensured, but the signal is sent to the driver to prompt the vehicle that the second signal is received to ask the driver to pay attention; also, whenever the vehicle is below the first threshold value and the first signal is received after the first signal or the second signal is received, the gear of the vehicle is automatically returned from the non-P gear to the P gear, without being affected by the previous vehicle operation.
Alternatively, the vehicle is in P-range as long as the first signal is received, and the range cannot be shifted until the first signal is not received.
Specifically, the automatic command that the vehicle automatically returns to the P gear from the non-P gear is executed as long as the first signal is received, and when the first signal is interrupted, the vehicle can be shifted to any gear from the P gear, so that the normal operation of the vehicle is not affected.
Optionally, the first signal includes a main drive door open signal and a brake pedal release signal.
Optionally, the second signal comprises a door sensor fault signal.
Optionally, the security prompt includes issuing a prompt voice and presenting a prompt text.
Optionally, the first threshold is 2Km/h.
Specifically, when the vehicle starts, the whole vehicle gear is in a non-P gear, and the vehicle speed is less than or equal to 2Km/h, when the main driving door is changed from a closed state to an open state, a main driving door opening signal is sent, a brake pedal is released, a brake pedal releasing signal is sent, and the gear can automatically control the automatic return to the P gear from the non-P gear, so that the vehicle is prevented from sliding and the safety of the vehicle and a driver is protected; in addition, when the fault signal of the vehicle door sensor is sent, the gear can automatically control the vehicle door to automatically return to the P gear from the non-P gear, but the automatic operation of the gear can only occur once, when the driver is in gear again, the electronic gear shifting will not perform the function of automatically returning to the P gear, the target gear can be normally hung in and kept, the instrument can carry out safety prompt, when the vehicle speed is less than or equal to 2Km/h again, and when the brake pedal is released, the fault signal of the vehicle door sensor always exists and defaults to the main driving vehicle door opening signal, so that the gear automatically returns to the P gear from the non-P gear again, and the situation that the driver does not slip after the driver leaves the vehicle is ensured.
The invention also provides a gear shifting control unit of the vehicle-associated main driving door, which comprises the following components:
an electronic shifter;
the vehicle door sensor and the brake pedal angle sensor are connected with the electronic gear shifter through the control unit;
and the vehicle speed sensor is connected with the control unit.
Specifically, an electronic gear shifter for controlling and monitoring gear is arranged in the gear shifting control unit, a vehicle door sensor and a brake pedal angle sensor are arranged on a vehicle door and a brake pedal, and when the vehicle speed sensor detects that the vehicle speed is less than or equal to 2Km/h, the control unit sends an instruction to the electronic gear shifter according to signals of the vehicle door sensor and the brake pedal angle sensor.
Optionally, a primary driver seat sensor is also included.
Specifically, set up the main seat sensor that drives in addition, can also further monitor whether the driver is in the car, if though the speed of a motor vehicle is less than or equal to 2Km/h, and door sensor discerns that the state is opened the door and brake pedal angle sensor discerns that brake pedal loosens the state, nevertheless probably the driver still is in the car, just will keep off the position automatically through electronic shifter and get back to the P and keep off, be inconvenient for driver's normal driving operation.
Optionally, the system further comprises a safety prompt sending module, and the safety prompt sending module is connected with the control unit.
Specifically, the safety prompt sending module can send a ' vehicle sliding risk ', please hang the P gear ', if the driver still forgets to record the P gear, the electronic gear shifter can automatically return to the P gear, and the vehicle is prevented from sliding.
The invention also provides an automobile which is characterized by comprising the gear shifting control unit for associating the main driving door with the automobile.
Specifically, after the gear shifting control unit is arranged on an automobile, when the automobile is in a driving state, the gear is in a non-P gear, and when the automobile speed is less than or equal to 2Km/h, the main driving door is changed from a closed state to an open state, and after a brake pedal is released, the safety of the automobile and a driver is protected in order to prevent the occurrence of a sliding situation, and the electronic gear shifter can switch the gear from the non-P gear to the P gear; in addition, when the vehicle door is damaged or the vehicle door sensor fails, the main driving vehicle door is in an open state due to the fact that the vehicle door sensor fails and defaults, the electronic gear shifter can keep the gear on the P gear, in order to ensure that a driver drives to a maintenance factory, the driver can shift gears again, the electronic gear shifter can not send an instruction of automatically returning to the P gear, the driver can normally shift into a target gear and keep the gear, and safety prompt is carried out through an instrument; in addition, the command of automatically returning to the P gear is always kept as long as the main driving door is changed from the closed state to the open state, the command of automatically returning to the P gear is not cleared until the vehicle door is changed to the closed state, and the command of automatically returning to the P gear is triggered once again when the main driving door is changed from the closed state to the open state next time.
When the vehicle is driven, the gear is in a non-P gear, and the vehicle speed is more than 2Km/h, when the main driving door is opened, after the brake pedal is released, the power is lost when a vehicle door signal is out of order, the electronic gear shifter can keep the gear, and the instrument can carry out safety prompt, so that the influence on the normal running of the whole vehicle can be prevented.
